0F SAME PLAGE.

' Letters Patent No. 96,380, dated November 2, ISGS).

The Schedule referred to in thele Letters Patent and making part of the same.

.l'o all @cham it may concern Be it known that I, M. H. BARNES, of the city and couutyoi' Peoria, and State of Illinois, have invented a new and improved Safety-Can and I do hereby declare lthat the following is a full, clear, and exact description of the construction and operation ,of the saine, reference bei'ng'had to' the accompanying drawings, making a part ot' this specification, in which- Figurel 1 is a side elevation, and

Figure 2, a central vertical section of the cam and hollow plug.

This invention has for its object to prevent the access of vflame to the explosive vapor that always lls the empty portions of cans partially full of oil, so that the 'can may be safely used to supply lighted lamps, or brought into any proximity, however close, with flame, without danger of exploding.

The invention consists in providing a spout, opening out of the bottom of the can, so that whatever oil may be in the Vessel, however small its quantity, shall shut loi the superjacent vapor from the. spoilt; and in forming the spout with one or two coils at the bottom, so arranged that they shall interpose no obstacle to the free escape of oil from the can, but shall prevent the return of all the oil in the spout to the can after the pouring has ceased, a small quantity of oil being retained in the coils, and there serving as a valve to prevent dame from communicating with the explosive vapor through the-spout.

Also, in providing, at the top of the can, a hollow plg that may be removed for the supplying of oilto the can, and that has'a hole in its top for ventilation, and that contains in its hollow chamber, between the vent-hole and the interior of the can, sponge or other porous material which shall also shut ofI" flame.

In the drawings- A is the can, and B the spout, the latter opening out of the bottom of the former, and having one and one-half or more coils, a, at its lower end.

On tipping the can so far that the oil inside it rises ter rises to the same height and enters and, flows out of thestraight part of the spout. On restoring the can to the horizontal, as soon as the oil has flowed Vdown out of the straight part ot' the spout, there. ceases to he suiiicient pressure to make it run up the opposite side of the coils, audit consequently stops flowing, filling the coils, and making it impossible for fiume to get at the vapor iu the-interior of the vessel. through the spout.

In the top of the can there is a tube, C, into which fits the hollow plug c, having a flange at its top to closely shut the tube when the plugis in place, and a vent-hole, c', through its head, and a sponge, c, or other porous material, within its` hollow chamber, and between the vent-hole and the inside of the can, which spongefreely admits air, but allows no ame to traverse it.

.lhus the interior ot? my can is guarded at 'all points against danger Iby re, and may be truiy said to be impregnable to this agent.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The tube B, opening out' of the bottoml of the canA, and provided at its lower end with the coils a, substantially as and for the purpose set forth.

2. The hollow plug C,.provided with the vent-hole c and porous material c", and arranged in respect to the can A, substantially-as described.

To the above specicat-ion of my improvement, I` have set my hand, this 4th day of September, 1869.'
